On the competition for available zinc: EXAFS investigation on model compounds
ثبت نشده
چکیده
Recently the generally accepted roles of protein-bound zinc in catalysis and structure stabilization were complemented by regulatory functions. An important question with respect to a regulatory function, however, concerns the controversially discussed concentration of free zinc ions in different physiological environments. If the transduction of a zinc signal is mediated by binding of zinc ions to zinc sensing proteins it is evident that free binding sites for zinc ions are a pre-requisite for such a regulation process.

On the competition for available zinc.
Extended x-ray absorption fine structure (EXAFS) spectroscopy was combined with thermodynamic and kinetic approaches to investigate zinc binding to a zinc finger (C2H2) and a tetrathiolate (C4) peptide. Both peptides represent structural zinc sites of proteins and rapidly bind a single zinc ion with picomolar dissociation constants. In competition with EDTA the transfer of peptide-bound zinc io...
متن کاملCompetition of zinc, cadmium and calcium for binding sites in sperm of trout and carp
Heavy metal pollutions of aquatic ecosystems have already raised many concerns on aquaticorganisms’health and survival especially on their sperm. The effects of a single metal on sperm may be totallydifferent from cocktail of several metals because of their interactions, so the effects of zinc, cadmium andcalcium on the trout and carp sperms and their competition have been examined by incubatio...

X-ray absorption spectroscopy (XAS), including extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) analysis, has been carried out at the Zn K edge of the N-terminal part of the integrase protein of the human immunodeficiency virus, type 2 (HIV-2), and of some zinc coordination compounds. In the presence of excess beta-mercaptoethanol, which was pres...
